电导法对7种观赏竹的抗寒性测定

Establishment of Cold Resistance of 7 Ornamental Bamboo Species by Electric Conductivity

选取了7种观赏竹竹种,以其离体叶片为试材,用电导法测定相对电导率。结果表明:7个竹种中平安竹和长叶苦竹抗寒性最强,凤尾竹抗寒性最弱,抗寒性由强至弱大致为:平安竹≈长叶苦竹>黄条金刚竹>鹅毛竹>菲白竹>铺地竹>凤尾竹。

The electrical conductivities of detached-leaf of 7 bamboo species were determined. The results were as follows ：The cold resistance of Pseudosasa japonica f. tsutsamiana and Pleioblastus chino f. hisauchii were the strongest among 7 bamboo species, and Bambusa multiplex f. fernleaf was the weakest. The cold resistance of 7 bamboo species was in ordet of Pseudosasa japonica f. tsutsamiana ≈Pleioblastus chino f. hisauchii 〉 Sasaella masamuneana f. aureostriata 〉 Shibataea chinensis〉 Arundinaria f ortunei〉 Arundinaria argonteostriata 〉 Bambusa multiplex f. fernleaf .
